In the following passage, some of the words have been left out. Read the passage carefully and select the correct answer for the given blank out of the given alternatives.

Internally, to some extent, India’s approach to trade remains a __(1)__ (leftover) of the pre-liberalization worldview, by which a __(2)__ (clutter) of specific incentives and policy measures for various sectors were expected to earn the foreign exchange needed to pay our foreign bills. An excessive focus on domestic demand and __(3)__ (must-have) things for imports had reduced the flexibility of our responses to world markets, the effects of which have proven too heavy to shake off. Even now, a credit subvention __(4)__ (small change) here or an export prop there passes for policy action, even as exporters have found their working capital squeezed by tax-refund delays ever since the goods and services tax came into force. Trade barriers erected by other countries are surely a __(5)__ (inhibiting effect), but raising our own tariffs is not the best response.
